EEE-HB1HR33R Equivalent & Substitute Parts

Part Overview

The EEE-HB1HR33R is a 0.33 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications with AEC-Q200 compliance and operates across -40°C to 105°C with a 2000-hour lifetime at 105°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-HB1HR33R is determined by the following critical parameters:

• Capacitance value: 0.33 µF (exact match required)
• Voltage rating: 50 V (minimum requirement)
• Tolerance: ±20% (acceptable range)
• Package configuration: Radial, Can - SMD (physical and electrical compatibility)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Operating temperature range: -40°C to 105°C (functional envelope)
• Polarization: Polar (electrical polarity requirement)
• Surface mount land size: 0.169" L x 0.169" W (4.30 mm x 4.30 mm) (footprint compatibility)

The substitute part UZT1HR33MCL1GB meets all critical substitution criteria, matching the capacitance, voltage rating, tolerance, package type, mounting configuration, operating temperature range, and surface mount land dimensions of the original component.

Parameter Comparison

Engineering Selection Recommendations

The UZT1HR33MCL1GB from Nichicon is a direct functional equivalent for the obsolete EEE-HB1HR33R. Both components share identical electrical specifications (0.33 µF, 50 V, ±20% tolerance) and physical compatibility (4.00 mm diameter, 4.30 mm x 4.30 mm land size). The substitute part is available in higher inventory quantities and maintains REACH compliance and EAR99 classification.

The primary engineering consideration is the reduced lifetime specification of the Nichicon part (1000 hours at 105°C versus 2000 hours for the Panasonic original). Applications requiring the full 2000-hour lifetime rating at elevated temperatures should evaluate this difference against specific system requirements. The Nichicon substitute exhibits slightly lower ripple current ratings at both 120 Hz and 10 kHz, which may be advantageous in noise-sensitive applications.

The substitute part is marked "Not For New Designs," indicating manufacturer discontinuation trajectory. For new production programs, evaluation of additional alternatives or long-term supply planning is recommended.

Frequently Asked Questions (FAQ)

Q: Can the UZT1HR33MCL1GB be used as a direct replacement on existing PCBs designed for the EEE-HB1HR33R?

A: Yes. Both components share identical surface mount land dimensions (0.169" L x 0.169" W / 4.30 mm x 4.30 mm) and physical diameter (0.157" / 4.00 mm). The substitute has a lower seated height (0.181" versus 0.228"), which presents no compatibility issues for standard PCB assembly.

Q: What is the impact of the reduced lifetime rating on the Nichicon substitute?

A: The UZT1HR33MCL1GB is rated for 1000 hours at 105°C compared to 2000 hours for the original. This affects long-term reliability in applications operating continuously at elevated temperatures. System designers must assess whether this reduced lifetime meets application requirements.

Q: Are there electrical performance differences between these parts?

A: Both components meet the same capacitance (0.33 µF), voltage (50 V), and tolerance (±20%) specifications. The Nichicon substitute exhibits lower ripple current ratings (2.8 mA at 120 Hz and 4.2 mA at 10 kHz versus 3 mA and 5.1 mA respectively), which may be beneficial in applications sensitive to ripple current generation.

Q: What is the significance of the product status markings?

A: The EEE-HB1HR33R is marked "Obsolete," indicating Panasonic has discontinued production. The UZT1HR33MCL1GB is marked "Not For New Designs," indicating Nichicon is phasing out this part. Both statuses indicate limited long-term availability and suggest evaluation of alternative solutions for new production programs.

Q: Are both parts compliant with automotive and regulatory requirements?

A: The original EEE-HB1HR33R carries AEC-Q200 automotive qualification. Both parts maintain REACH compliance and EAR99 export classification. The Nichicon substitute does not specify AEC-Q200 rating; applications requiring automotive qualification should confirm compliance with system requirements.
